Las macroenzimas son complejos de elevado peso molecular que podrían incrementar la actividad enzimática sérica en ausencia de signos y síntomas.Se pueden detectar al ser precipitadas con polietilenglicol. El objetivo del trabajo fue determinar la actividad de las aminotransferasas por el método IFCC, calcular y comparar la media del porcentaje de actividad precipitable (x̄), su intervalo de confianza del 95% (IC95%) y el desvío estándar (DE). Se trabajó con individuos con (n=42) y sin hipertransaminasemia (n=22). Los resultados para uno y otro fueron: porcentaje de actividad precipitable con polietilenglicol (%PPA) (x̄, DE, IC95%) = (28%; 1,82; 27,45%-28,55% y 44%; 24,52; 32,84%-55,16%) y (15%; 13,03; 11,01%-18,99% y 25%; 9,1; 20,96%-29,04%) para ALT y AST, respectivamente (p=0,003 y p=0,001; p<0,05). En conclusión, la estimación de la media poblacional podría ser más precisa en individuos con hipertransaminasemia.

Macroenzymes are high-molecular-mass complexes that might increase the serum enzymatic activity in the absence of symptoms. An easy-touse method to detect them is the polyethylene glycol precipitation. The aim of this study was to determine aminotransferases activity using the IFCC method, and to calculate the mean percentage of precipitable activity (x̄), its 95% confidence interval (CI95%), and the standard deviation (SD). The study included individuals with (n=42) and without hypertransaminasemia (n=22). The results were: percentaje of precipitable activity (%PPA) (x̄, SD, CI95%) = (28%; 1.82; 27.45%-28.55% and 44%; 24.52; 32.84%-55.16%) and (15%; 13.03; 11.01%-18.99% and 25%; 9.1;20.96%-29.04%) for ALT and AST, respectively (p=0.003 and p=0.001; p<0.05). In conclusion, the estimation of the population mean could be more precise in individuals with hypertransaminasemia.
